+	  This gives you access to some advanced options for the PS3. The

+	  it possible to better control the kernel configuration if you know
+	  what you are doing.
+
+	  Note that the answer to this question won't directly affect the
+	  kernel: saying N will just cause the configurator to skip all
+	  the questions about these options.
